I was in my reloading room the other night and got bored.
So i took a Privi 9.3x62 case and ran it into the neck of my 338 mag die.
I then seated a 250 grain Hornaday spire point into the case.
Now im thinking if i wasnt pushing 70 this might be worth looking at. lol

It is a waste of time when you can just go with a 338-06 and use common brass and easy to get dies.
I say this as I just last week made a 375x62; from 9.3x62 brass. I did this so I can use standard 9.3x62 dies and not pay $200 for a set of dies.
Pushing 70 is nothing; you got 30 more years to go.

This is already a commercial calibre. Developed by Werner Reb it is called the 8.5x63. It is merely the 9.3x62 necked down to 338. Shoulder may be slightly different than the x62 case. Likely closer to a 338-06 imp

Thanks for the replys. Ill do a search on the 8.5x63

Seems to me might have it backwards, the .338 wIN MAGNUM necked up to 9.3 sounds better to me, but then in both cases we have the 9.3x64 a grand beltless caliber...I built a few 9.5x62s (375/9.3x62) and they duplicated a 375 H&H with a 300 gr. bullet at 2500 FPS..All decent rounds but I personally see little need for wildcats these days..

DPCD.
Not sure I understand?? How can you use 9.3x62 dies to load a 375x62 wildcat..One of my favorites as for as wildcats go, but presently my big bore wildcat is the 8mm/06 Ackley IMP on a small ring Brno mod 21 rifle. Im really liking this one and all I had to do was rechamber it..Its an elk killer for sure about like a 338-06 best I can describe.

remember, the x62 is basically a 30-06-case
the x64 is basically a short HH de-belted (that's how we used to make cases)

so, 338-06 or 338winmag equals, either way you cut it

The 30-06 is basically a 9.3x62 case?? not the case at all (pun intended) and the old use of 06 cases to shoot 9.3 bullets was a bad practice..and consider by some as dangerous..I will refer you to African Dangerous cartridges on t he subject, as I think you have a copy of it. I agree with that in that has been my experience of problems in case life, accuracy, and brass failures as well as feeding problems etc..and 9.3x62 brass today is more available and cheap as 30-06 stuff, mostly due to PPU..

Werner Reb recomends using 35 Whelan brass to form the 8,5.
The same bolt/bolthead are used to make 3006, 308w, 9,3*62 and 6,5*55 rifles.

No the base of the 9.3x62 is wider than the 30-06, so it would also apply to the 35 Whelen, and yes it can be done and Ive done it, but its a poor practice and can be dangerous,,It was put to use out of necessity in years past., but not recommended today..Again go to African Dangerous Game Cartridges by Pierre van der WAlt..on the subject. However if one used an 06 chamber reamer and necked up to 9.3x62, that would be a go..

It exists and is called the 366 Alaskan. And a friend of mine here in Maine took a 358 Norma Magnum, necked it up to .366 and called it the 366 Barbie in honor of his wife.

Kabluey here also has one.

All in all the 9.3x62 and the 9.3x64 are the best of the 9.3, the most that can be gotten form a case of that size..Ive wildcatted to the 375x62 and got 2500 fps with a 300 gr. flat base bullet..Pretty awesome and with a std 98 Mauser action, same with the 9.3x64 to 375 x 64...but today I shoot the 375 Ruger and its the best...

You use a 9.3x62 sizer and a .373 expander.
I have done it.
Now, some of these other calibers require expensive custom dies. I have never seen that 8.5 mentioned.
Back to the OP's wanting a 338 based on the 9.3x62 case: not worth the expense. Even if you can get someone to make you dies. One set of custom dies will cost you $500.

Thank you..

Wildcatting is supposed to be needfull, none of this is,its guess and by gosh..The 93x62 is a better caliber for big game than the 338/x62 and if that doesn't work for you the 9.3x64 is the clone of the 375 sans a belt..and is declared basically the 375 of Europe by many..

Pretty sure Werner Reb designed the 8,5x63 on the 7x64 case, which is a slightly different diameter again if memory serves.
As for the 9,3 if you need more than the 9,3x64 Brenneke there’s always the 9,3x70DWM. Triebels in Germany is where to start looking for obscure metric dies

This is a wast of time and money; what very little you will gain over a 338-06 will be dearly paid for in custom dies and harder to get brass. In case I didn't say that somewhere before. It's only $ though....

I agree it doesn't seem worth the effort. A .338-62mm case would hold a few more grains of water than the .338-06 case. But you'd have to have a special reamer made to cut the chamber and 9.3x62 brass isn't widely available.

Chambering in 338-06-AI would make up the few grains additional capacity your .338-62 cartridge would have plus you could shoot standard 338-06 ammo. Chamber reamers for 338-06-AI already exist and can be rented from multiple sources. Factory made 338-06 cases can be purchased but can also be formed from 30-06 cases.

Simply put, your .338-62 would get you 338-06-AI performance by going at it the hard way.

And then there's the .338 Scovill version of the .338 Hawk made by Dave Scovill, editor of "Rifle" and "Handloaders", from 9.3 X 62 cases. QUAL-CART has cases.

That's exactly what I was thinking!

Yep decided to go with a plain old 338-06 with a Shilen barrel.

Or the 340 Howell

I used the 338-06 both standard and IMP back in the day when the 35 Whelen was king of the O6 babys. I used it too, a great caliber..

Today I see the .338 win. as the best of the bunch and its not a wildcat, I have a hard time deciding what I like best, the 9.3x62 or the .338 Win mag, guess for black timber elk the 9.3 is my favorite, and the 338 for open country, but there again its baloney, the 338 WM and the 375 Ruger cover all the bases, I just dont need any wildcat these days, the differnce in men and boys is the cost of the toys, and wildcats COST..

If I ever have to pick one caliber for all my big game hunting, when the liberals take over the world, it will be the 30-06, its never failed me..

BTW, 9.3x62 brass has and is available, PPU distributes it with Midway, Grafs, ET brass, Ive never been out in fact I just received 300 cases from grafs or midway, not sure which..I still shoot the 9.3x62, my two hunting loads are the Hornaday 286 INterlock and the 250 gr. accubond with a case full of H414 or WW760..66to 67 grs for those two..I like the 300 gr.swift but not much use for it these days, but I shot a lot of buffalo with that bullet back in the day..

This would essentially be the 338 SABI of SA design.

Ray is right along with dpcd.

I have a 338-06 and a 35 Whelen both rebored and rechambered pre-64 M-70s. Original iron sights and Lyman 48s. No real dangerous game rifles without iron sights.

Backing these two up are a M-70 in 338 WM and an original M-70 in 375 H&H. I prefer the original 375 Holland over any 375 because it has been working since its inception.
More of everything has been killed with a 375
than just about any caliber in Africa.

The 338-06 is a modern version of the 333 OKH.
Keith said it worked for him. There will always be 06 and 270 brass.
In Handloader magazine a few years back, they came out with the 338 HGT on the 270 case. It produced amazing ballistics when pushed-just like a 338-06 Improved. Mine just keeps on with an old Super Grade stock.

What's another 500.00 to a gun crank willing to spend thousands.

Bringing actions up to modern standards.

I never thought Id abandon the great 375 H&H, and will always have one I think..but I bought a Ruger 77 in 375 Ruger because I got a hell of a deal on it..I bought a set of dies and some brass to play with it..Wow! this is one hell of a caliber, and better than any other 375 or so it seems to me and only to one degree or another, but it passed muster big time, Its just a better design and function IMO.. I feel guilty btw..
